The new Caliber-Matched Gas System (CAMGAS) barrels from PROOF Research are designed to eliminate the problems associated with AR-10 platforms chambered in 6.5 Creedmoor and .260 Rem. The new design works by tuning the gas system with the specific cartridge/barrel length combination used in a particular rifle.

"By moving the gas port, the pressure in the bore is given time to reduce to that comparable of a .308 Win. with a rifle-length gas system, which is what the 308AR/AR-10 system was designed around," said Greg Hamilton, PROOF's research and development weapons specialist "The recoil impulse is noticeably smoother, which helps keep you on target while taking advantage of a more efficient projectile. Case extraction is also easier, with less case-head smearing, so the brass is in much better condition for reloading."

Before the new design, those who shot AR-platform rifles chambered in 6.5 Creedmoor or .260 Rem. dealt with significant pressures in their gas system, necessitating the use of parts like clipping buffer springs, different buffer weights and adjustable gas blocks in order to have a functioning rifle.

The company is now offering CAMGAS barrels for 6.5 Creedmoor and .260 Rem. in 20-, 22- and 24-inch barrel lengths. Each barrel comes with a custom-length gas tube that is easy to install. The suggested retail price for a CAMGAS barrel is $940.
